we need module for whmcs that connect to openprovider api and create lciense for us and we need ONLY the license section their docs are here:
[url removed, login to view]
we want module work in this :
create product per plesk license (for example create one product and call it plesk 11 then create another product and call it plesk 12 then create new product and call it plesk 10 and etc) and then create configurable option in whmcs per product and every configurable option has 11 options ( 9 plesk option, 2 sites, 1 version, 2 site, 6 language pack, and some bit extra)
and when you want send create lciense api to open provider you should include all configurable option .
maybe their documents does not include some of these so please execute api once then do not tell it needs some feature more and it takes more time and it needs more money all of things i know about api i tell you here,
thanks all of oyu.
